Experience hacking iPhone, No Experience with Wii

Hello! Posting in the Noob forum, as required. After browsing as a guest for a while, and reading in circles, I figured this was the best way to proceed. I'm mostly interested in using my Wii for emu play, and like to take mods step by step. I'm very cautious with my hardware.

I have 0 experience hacking a Wii, and would like some direction, where to start, what to read first.
